MECHANISM FOR DRIVING AND CONTROLLING ELECTRICITY METERS.

Application filed April 11, 1927, Serial No.

The invention relates to means fordriv' ing and controlling electricity meters, and

will be in part further set forth hereinafter,

and in part will be obvious herefr'orn or may be learned by practicing the invention.

The inventionconsists in the novelpart's, constructions, combinations and arrangements herein shown and described.

The accompanying drawings, herein referred to and constituting a part hereof, i1; lustrate an embodiment and apracticing of the invention, and together with the description serve to explain the principles thereof. Of tlie drawings:-;"

Fig. 1 is an elevation, with parts omitted, of a mechanism embodying the invention; Y

I 2 is a top plan, on line .2-2nof Fig.1, withparts in section, and showing the reg s-v tering mechanism, which is omitted from Fig. 1; p f i Fig. 3 is an enlarged, fragmentary elevae tion of parts near the upper, right-hand part ofFi'g. 1; and

Fig. 4 is ajfragmentary,enlarged elevation looking'from line 4-4 of Fig. 3 in the direction of the arrows and e Fig. 5 is a fragmentary, enlarged detail'of a core terminal adjustment. 'Ihe'invention is directed primarily to ob viating and preventing error producing disturb ances or aberrations in the measuring and recording of electric energy consumption,

due'tothe friction and inertia ofthe mechanism of the meter: and the consumptionof.

energy in driving the same. ,This object is effected, broadly considered, by providing a. separate driving means for the registering mechanism, thereby removing thewo'rk of overcoming inertia, the mechanical energy consumed in driving and other detracting and disturbing factors from the electro-magnetically driven meter element, said element being thus mainly utilized in governingthe speed ofthe meter disc or equivalent mechanism proportionally to the energy consumption of the circuit. n I k, I

Moreparticularly, I-provide means for pract-iciii g it, whereby drivingmeans, electromagi;

tit: or otherwise, areprovided an the 132,949,. and in Switzerland April 20, 1926.

registering mechanism, and separate electromagnetically driven and controlled means are 'provided for governing the thus driven registering means in conformity.or'propon tion to the electric-energy consumption of the. circuit. Thus the means for g0verning,but not driving,jthe registering means are freed fromjthe disturbances due to or arising out I ofthework of driving the registering mechanism. v I .Anotherobject of the invention is to re move other errorproducing or measurementdisturbing actionsflor influences which may exist. ifFor example, in many meters devices are provided for producing a supplementary torque on the meter disc, or equivalent ele merit, for instance, duringt-he starting period of the current flow. One kind of device for effecting such a supplementary torque is usually called a dispersion wing or starting Win i "1 .YVVhile such devices have'been either essential or desirable Wltll various meters, yet their use has been accompanied with certain un- I favorable or disturbingresults, such, for instance, as causing slippageofthe meter disc,

ducing devices are employed,. it is desirable to ke'epjthem ofras low power consumption as possible. By my present invention, such de vices,even when used, may be reduced in size or power to, a minimum, as when the registering mechanism is separately or independ ently driven, such a device need only have sufficient power to overcome the inertia ofthe .meteridisc shaft bearings.

of the invention, but is preferably electro magnetically driven is so shown de scribed m the present preferred embodiment.

and when suchysupp'lementary torqi e pro Referring now in detail to the present preferred embodiment of the invention; illustrated by Way of example inthe accompanying drawings, a general structure of a meter isshowin' iii-any parts notrelating to theypres. ent invention being omitted 101' the sake, of

clearness. As shown, a meter casing 1 has af-i fltixed to the i'nter orthereot a frame 2,wh:ich

supports a'core 8., or any suitahle'form, and provided with series or pressure coil 5. t

Aqn'icter disc 8 is mounted on aspindle or shaft SQmounted in endbearingsll and 12, carried supports 13 and 14, supported on the frame The connections from the 'me'ter disc shaft: to the registering mechag nism comprise a worm l9, formed on the shaftS; and meshing therewith is a WOI'III- Wheel 20, mounted on andhaving'its hub 21 fixed to? asha l't 22, mounted in hearings, 23 and QtQsupported from the frame of the registering mechanism. Aipinion Q'T-is fixed on" the end of the shaft 22,: which-pinion meshes with a gear wl1eelj 28 of the register- 'ing mechanism 29. The registering mecha;

nism maybe; of any "known or suitablekind adapted for the, particular kind of {meter and the conditions under which it is operated; and the uses to which it is pu Q 1 In many. electricity meters a'device iseme o ployed for overcoming the friction and inertia of the meter in starting, such devices lie starting wing? Such a deviceima y be used,

if desired, in connection withjthe present inventroin and is so shown in the draw ng; In

said embodiment a supporting member" or bracket 31 off non-magnetic metal is sup: ported by screws 3 2,threaded into the meter core. Fixed to this supporting} member is a piece or wing33 of magnetic inetal',fwhich serves to impart'an initialtoique to the meter disc during the early 'orjloW-currentstage 1n the operation of the, meter, Sofar as concerns the main features of the" present v in} vent-ion; the'use or omission ,ofthe starting wing or equivalent device is immaterial} Referring now to theembodied "form of means for "drivingjthe registeringmechanism otherwise than through the'lordinarymeter disc, a disc 37 is mounted on and its hub 36 is fiXedto the shaft 2210f thefregistering mechanism, this .disc being of aluminum; or other, nonmagnetic man; I The embo ied form of means forelectro-magnetically driv ing the disci37 comprises an elongated core terminal or projection 38, fixed to'thelcore at one end or pole of the pressure. coil 5,;this pole SSterminating adjacent to oneifaceof thedisc -37, "If desirechtl'iis' pole be provided-witha positioning, or adjusting; device 39, (Fig 5:) tively menace may be varied the driving action upon the disc 0} control ,The oo-operatingcore pole terminal or prof current coils sand a in combination registering mech wherehyfits'" position j rel'a jection comprises a member40 fixed to the,

meter coreon the outer sideof the pressure coil 5, and this member has its other end closely adjacent to'the opposite side of the disc. 37. from the-core terminal 38;. For the purpose ofcreating a torque component tend- ;ing to rotate the disc 37, the core terminal 40 is i-ro-vided with so aerated roectin ends l b 41 and 42, extending toward the disc 37.

The projecting end 41 hasia cop-per ring 4&3 mounted thereon, for the purpose of influencing th'ejmagnetic field soas tov provide the required torque component for rotating the disc It will be understood, that sovfa r as concerns certain of the broader features ofltheoinyentiomthe drive for thejregistering mechanism could be, of, some other form,

as for instance amechanicaldrive; the meter d sc in such case also, being connected to control the speed of the register driving shaft proportionately to the'e'nergy consump Q -Q a f F-rom all the foregoing it will beunder stood that mechanism hasbeen providedfreal;
